knowing what to do for openzdk, i loaded the roms (zipped) into the correct folder and deployed. so, i start up my zune, and then VBZ, one of two things happen, either -
1. the game goes onto the zune logo loading screen then blacks out and returns to zune home menu
OR
2. the game loads to menu, but does not respond to any commands.

I am running the version with the updated menu to try and solve problems, but to no avail.

Also, if you have a Pin, after exiting a ZDK app that pin will not work. You must restart your Zune. This does provide an awesome way for you to fool your friends that there is not way to get in to your private files.
